V2 is related to which aspect of takeoff performance?

1. Best rate of climb

2. Takeoff safety speed

3. Stalling speed in landing configuration

4. Speed for best angle of climb

The correct answer is: Takeoff safety speed

V2 is defined as the takeoff safety speed. This speed is critical during the takeoff phase because it represents the minimum speed that must be achieved before reaching the end of the runway in order to ensure safe aircraft performance during the event of an engine failure. Achieving V2 allows the aircraft to maintain a safe climb gradient, ensuring that it can clear obstacles and maintain controlled flight even if one of its engines fails shortly after takeoff. In contrast, the other options refer to different aspects of flight performance. The best rate of climb relates to the speed that provides the highest altitude gain over time, which is different from V2. Stalling speed in landing configuration focuses on the minimum speed at which the aircraft can maintain level flight in a specific configuration, making it distinct from V2 as well. Lastly, the speed for best angle of climb pertains to maximizing altitude gain over distance rather than focusing on safety during takeoff, again setting it apart from the concept of V2.
